Reported: 2017-03-01 (March 1, 2017) · Model years: 2017
REV Ambulance Group Orlando, INC. (REV) is recalling certain 2017 Wheeled Coach Type I, McCoy-Miller Type I, Frontline Type I, Marque Type I, and Road Rescue Type I ambulances, built on Ford F-350, F-450, or F-550 chassis equipped with Compressible Liquid Adaptive Suspension Systems (C.L.A.S.S.) made by LiquidSpring. Due to an incorrect torque specification, the rear brake caliper banjo bolts may have been overtightened.
Consequence: The improperly tightened banjo bolts may result in a partial or complete loss of rear brake power, increasing the risk of a crash.
Remedy: REV will notify owners, and LiquidSpring dealers will replace the rear brake banjo bolts, free of charge. The recall began during April 2017. Owners may contact LiquidSpring customer service at 1-765-474-7816 extension 1 or by email at [email protected] or REV customer service at 1-800-628-8178.
Reported: 2018-09-08 (September 8, 2018) · Model years: 2017, 2018
REV Ambulance Group Orland, Inc. (REV) is recalling certain 2017-2018 Road Rescue, Marque, Wheeled Coach, Frontline, and McCoy Miller Type I and Type III ambulances, equipped with Whelen accessory brake lights. Depending on the specific wiring of the vehicle, these brake lights may illuminate when the brake pedal has not been pressed. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."
Consequence: If the brake lights incorrectly illuminate, it can confuse other drivers, possibly increasing the risk of a crash.
Remedy: REV will notify owners, and Whelen will replace the brake lights, free of charge. The recall began October 19, 2018. Owners may contact REV customer service at 1-855-661-9232.

REV Ambulance Group Orlando, Inc. (REV) is recalling certain 2018-2020 Type 1 ambulances built on Ram 4500 and 5500 chassis equipped with Compressible Liquid Adaptive Suspension Systems (C.L.A.S.S.), part numbers DS135RS3A, DS135RS3AF and DS135RS3-DM. The rear brake caliper flexible line may have been routed so that it contacts a suspension component, possibly causing excessive wear and a loss of rear brakes.
Consequence: A worn rear brake caliper flexible line may cause brake fluid leakage which may result in a partial or complete loss of the rear brakes, increasing the risk of a crash.
Remedy: REV will notify owners, and dealers will dealers inspect the rear brake caliper flexible lines for wear and install a kit to modify the rear brake caliper flexible line mounting, and if necessary, a kit to replace worn brake lines, free of charge. The recall began July 15, 2020. Owners may contact REV customer service at 1-855-661-9232.

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
